Urban Criteria for Settlements (UN):

Municipalities (baladiyas).

Administrative Population Edits and Notes:

Population data were extrapolated to 1995 and 2000 using growth rates derived from United Nations national level estimates and projections.

Administrative Spatial Edits and Notes:

Boundaries were digitized from the CIA map "Libya" dated 5-93. See: http://www.lib.utexas.edu/Libs/PCL/Map_collection/africa/Libya.GIF. Projection information was included on the map, but the scale was not. Due to the small cartographic scale of the map, however, the accuracy of the boundaries is very low. While this may not be important in the uninhabited desert areas, it may lead to errors in the urbanized coastal regions-- particularly around Tripoli.
